They spend a lot of their time hopping up and down on the spot making soft squeaking calls that sound like real-life geese, giving them a hyperactive personality. This gives them restless minds, indulging them into having long philosophical discussions, with themselves or with the greenbottles.

In this game, Minisaurus are slow-moving creatures who live in herds. They wear red and green chequered overalls and have two spindly wings on their backs. They have frills on their heads like a cockerel and brown spots on their yellow bodies as well as oversized beaks and arms. They only appear in the Minisaurus Plain in Rayman Revolution. According to a baby Globox, he owns them, but the pirates' interference in the world, such as the destruction of the Heart of the World, has driven them mad, and now they eat the Popolopoïs. Rayman can daze them, but they can bite him back. Minisaurus are larger versions of Denys, creatures found in cages in the PlayStation version of Rayman 2. Like Denys, the baby Minisaurus emit a high-pitched squeaking and bounce around when they are separated from their parents. The noise can be heard from the Pier. Baby Minisaurus are quite calm, not attacking Rayman when he comes into sight, unlike the adults, who relentlessly chase down intruders. There are only two babies and four adults in the whole game.

It is possible to lure a Minisaurus off of a cliff. First, Rayman needs to alert their attention, then run towards the cliff near the Pier and jump off. The Minisaurus will likely jump off the cliff along with Rayman. They will continue hugging the cliff wall and wade into the piranha-infested water. They will not appear back on the cliff when the player gets back up. However, if Rayman dies or exits the level, the Minisaurus will reappear.
